Error EABO Keithley 7001

[Dowouii]

Hello everybody!

I'm curently working with a :

Data Acquisition Model (Keithley 7001),

PCI-GPIB IEE 488,

Labview 6.1

Measurement and Automation Explorer 2.2.0.3010

Windows 2000 5.0

When I try to "Communicate with my instrument" with MAX, I have always the same error EABO. I had a look on the documentation of Keitlhey and I have to send EOS at the end of the message. I tried to change the timeout condition, I increase it but nothing works...Moreover I installed the last driver for the PCI-GPIB.

The problem is I can "Query" but not "Read".

If someone could give me some advice, it will be appreciated!!

Thanks,

What do you mean when you say that you can query but not read?  I am not familiar with this instrument, but in most cases there will be nothing to read unless you have first written a command to the device.

A query is the same as performing a write then a read.

Hello,

So if Query means Write and Read, I think I haven't a problem....
When you work in MAX to configure your instrument, it says to SCAN and after to COMMUNICATE WITH YOUR INSTRUMENT. For this you ave to QUERY and after to READ.
When I QUERY I have an answer but when I READ I have an error message EABO.
Moroever, I did a programm on Labview but it doesn't work: I have an error which means problem with my driver. So I really think there is a problem.
If you have an idea, it's welcomed 🙂

Query is write and read so that is one problem less.
What kind of problem do you have in your LabVIEW program?
